Description

Technical Field

[0001] This utility model relates to the field of grilling technology, and in particular to a smokeless grilling air duct structure. Background Technology

[0002] Existing smokeless grills mainly achieve a smokeless effect by using an internal fan to remove cooking fumes.

[0003] However, in order to ensure the personal safety of users, existing grills have protective nets at the air inlet and outlet of the fan to prevent people's fingers from touching the running fan wheel and causing injury.

[0004] Based on the above, the existing technology has the following technical problem: the effectiveness of the smoke-free function is limited by the ratio of the inlet area to the outlet area. In actual exhaust, the outlet area needs to be slightly larger than the inlet area to achieve better extraction efficiency and a better smoke-free effect. However, the baffle mesh affects exhaust and is prone to further affecting exhaust due to oil fume buildup, requiring further improvement. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a smokeless grill duct structure that eliminates the air outlet obstruction mesh and incorporates a detection sensor to detect the position of the oil collection box, thereby ensuring the safety of the air outlet.

[0006] A smokeless grill air duct structure designed for this purpose includes a grill body, the grill body is provided with an air duct, an air inlet is provided on one side of the air duct and an air outlet is provided on the other side, and a ventilation opening is provided on the outer wall surface of the grill body.

[0007] A fan is installed inside the air duct, and a circuit board electrically connected to the fan is installed on the grill body.

[0008] An oil collection box is detachably connected to the wall of the grill body, which has a ventilation vent. The grill body is equipped with a detection sensor to detect whether the oil collection box is installed in place. The detection sensor is electrically connected to the circuit board.

[0009] Preferably, the detection sensor is disposed inside the ventilation opening.

[0010] Preferably, the detection sensor is a contact sensor;

[0011] When the oil receiving box is installed in the predetermined position, the oil receiving box comes into contact with the sensing end of the detection sensor, and the detection sensor sends an electrical signal to the circuit board.

[0012] Preferably, the detection sensor is a micro switch, a touch switch, or a spring switch.

[0013] Preferably, the air inlet is provided with a barrier mesh.

[0014] Compared with existing technologies, this invention eliminates the obstruction mesh at the air outlet, increasing the ventilation volume. Simultaneously, a detection sensor is installed to check if the oil collection box is in place, thus preventing the air vent from being open and preventing users from inserting fingers or other objects into the air duct, causing injury. This ensures user safety and the normal operation of the product. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the oil receiving box in its assembled state.

[0016] Figure 2 This is a schematic diagram of the oil collection box in a disassembled state. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] See Figures 1-2 A smokeless grill duct structure includes a grill body 10, an air duct 20, an air inlet 110 on one side and an air outlet 130 on the other side, and a connecting vent 140 on the outer wall of the grill body 10. A fan 30 is installed inside the air duct 20, and a circuit board electrically connected to the fan 30 is installed on the grill body 10. An oil collection box 40 is detachably connected to the wall of the grill body 10 with the connecting vent 140. A detection sensor 50 is installed on the grill body 10 to detect whether the oil collection box 40 is properly installed, and the detection sensor 50 is electrically connected to the circuit board. Compared with the prior art, this embodiment eliminates the obstruction mesh at the air outlet, increasing the ventilation volume of the air outlet. Simultaneously, a detection sensor is installed to detect whether the oil collection box is in place, thereby preventing the ventilation opening from being open and preventing users from inserting their fingers or other objects into the air duct through the ventilation opening, which could cause injury. This ensures user safety while guaranteeing the normal use of the product.

[0019] See Figure 1 and Figure 2 The detection sensor 50 is disposed within the ventilation opening 140. In this embodiment, disposing of the detection sensor 50 within the ventilation opening 140 facilitates its assembly and utilizes the space of the ventilation opening 140, eliminating the need for additional space on the grill body 10 for installing the detection sensor 50, thus facilitating product processing and production.

[0020] See Figure 1 and Figure 2 The detection sensor 50 is a contact sensor; when the oil receiving box 40 is installed in the predetermined position, the oil receiving box 40 comes into contact with the sensing end of the detection sensor 50, and the detection sensor 50 sends an electrical signal to the circuit board.

[0021] The function of the detection sensor 50 is to send an electrical signal to the circuit board when the oil receiving box 40 is installed in the predetermined position. In this mode, the circuit board control circuit powers on the fan 30. When the detection sensor 50 does not send an electrical signal to the circuit board, the circuit board control circuit is in a de-powered state. In this mode, the fan 30 cannot start, and the ventilation vent 140 remains open. Even if foreign objects enter the air duct 20, there will be no safety hazard.

[0022] Furthermore, the detection sensor 50 is a micro switch, a touch switch, or a spring switch. When the oil receiving box 40 is installed in the predetermined position, the oil receiving box 40 is triggered by the sensing end of the detection sensor 50.

[0023] See Figure 1 The air inlet 110 is equipped with a barrier mesh 120.

[0024] In this invention, the oil collection box 40 can be connected and assembled with the grill body 10 using the installation structure of existing similar products. For example, it can be assembled with the grill body 10 by front and rear plug-in connection, by snap-fit ​​structure, or by magnetic connection.
